I'm pretty new to revolvers and am trying to do my research on one I'm interested in. As was stated in the title, it's a model 10-7, 2 inch barrel, 6 shot, exposed hammer, square grip. I believe the serial number is 6D64391. There is also a secondary number I've found in a couple places of 47636. Also marked in a couple places is a stamp of L19 (maybe a police marking of some sort?) Thanks so much for any info!
